This romantic and sometimes ribald historical farce finds nobleman Guerrando (Tony Curtis) knighted in the days before the Crusades. He inherits a castle, tax-collecting rights, first choice of all the fair young maidens of the region, and a draft notice from the King. Boccadoro (Monica Vitti) is the liberal-minded forest woman who catches the eye of the young nobleman. Courtship, love and marriage follows, but the wedding night is interrupted by a call to arms.

The young bride follows her husband's troop at a distance hoping to get her hand on the coveted key to the lock.
